whats your base settings for initial start up?
 

i have a turbo bp using miata 1.6 cas sensor, 1.6 coil and igniters. im using turbo coupe 370cc injectors with a resistor pack. i copied my buddies tune from his megasquirted miata but its not working, it keeps backfiring like a shotgun and not starting. we got it to idle but it only idles for maybe 45sec then stops running and wont restart. if you try to give it gas while its idling it instantly dies...

ive checked for vacuum leaks and found none.

MAP sensor settings are wrong. You can't just copy maps and expect it to work.

JT, this is Vlad.
I'll try to make some time tomorrow and stop by and see if I can help, but I think Andrew is right: all your calibrations are fucked and you need to start fresh instead of using Seans map

sweet thanks... the sooner the better... i dont want to have to switch back all my stock stuff...

ok so now i have everyt thing reading correctly. now it cranks and doest start. it back fires like a shot gun sometimes. when cranking and will sputter and try to start but wont start. i pulled the spark plugs and they are fouled pretty bad... i cleaned them but it didnt change anything. ive been working on this for a few days but i cant figure this thing out.

i dont know how to post data logs or tunes.

too much fuel on startup.
